Below are all of David Shaw's postings, with the most recent are at the bottom of the page.I live in Derby(DE24). Since the recent work carried out on the Waltham transmitter, we have experienced very intermittent reception on all BBC channels (pixelation occuring on a random basis, starting anywhere between a few seconds and a few minutes from switching on and sometimes making the picture unwatchable). This only occurs with our upstairs TV, which uses a separate digital tuner since it only has an analogue tuner - the downstairs (digital) TV and DVD tuners works fine. I have tried retuning (Full Scan Replace Existing Services) and this makes no difference. Any advice would be welcome.

Regarding the problems I referred to yesterday: I have just tried a Manual Scan on Channel 49 and now have a fine (non-pixelated) picture on all of the BBC channels - apart from BBC1 (!). I noticed this morning that we had completely lost the picture on some ITV channels but again a Manual Scan on the appropriate channel (54) brought the pictures back. So the advice provided by UK Digital to try a Manual Scan if the "Full Scan - Replace Existing Services" doesn't work is obviously something well worth trying!

Dave Lindsay: Thankyou for your advice. You were absolutely correct, BBC1 on TV channel 1 is indeed tuned into Channel 43 which is operating on low power (unlike the other BBC channels which are all tuned into Channel 49 and are therefore OK since this channel is operating on a much higher power). I have also now found BBC1 on TV channel 800 which is tuned into channel 49 and is therefore, not surprisingly, OK.

David Welsh: I live in Derby near to the edge of the area covered by the Waltham transmitter. The reception is fine for all of the channels apart from those from the BBC. These all experience some degree of pixelation, sometimes so significant that the picture breaks up completely. This happens on a random basis - sometimes within only a few minutes of starting to view the channel and on other occasions after about 30 to 40 minutes. After retuning (using "Full Scan - Replace Existing Services")the problem can disappear for a few minutes but always comes back eventually, sometimes within few minutes.
